History: The son of one of the 25th century's greatest scientific
geniuses, Marvo had inherited his father's intellect, and despite only being
fifteen years old, he possessed scientific knowledge comparable to an average
scientist of forty, learning subconsciously while sleeping thanks to the
super hypnobioscope; in recognition of his genius, the government has awarded
him a plus sign at the end of his name, a privilege given to only the top
ten minds of Earth. Accompanied by his friend Bud, Marvo discovered a world
inside the hollow Earth, where he discovers prehistoric monsters, and then
became the first human to visit a new planet which had entered the solar
system, discovering it was the homeworld of the hostile insectoid Antarenes,
who were plotting to destroy Earth so that Antar could take its place orbiting
the Sun. Naturally Marvo and Bud found this objectionable, and they destroyed
the Antarenes' guidance and propulsion systems, sending the planet spinning
off back out of Earth's solar system.
